About the NetBackup preinstall checker

The NetBackup installer includes a preinstall checker. This feature helps to determine if your computer is ready for a successful installation or upgrade.

The check runs automatically when you start an upgrade. The results of the check are shown at the following point:

  • UNIX or Linux upgrade script

    After you accept the end user license agreement but before the installation starts.

  • Windows installation wizard

    On the Ready to Install the Program screen, where the Installation Summary appears.

Additionally, you can run the preinstall checker through VxUpdate. See About VxUpdate.

NetBackup uses a preinstallation program that does a check at the beginning of installations or upgrades. The check looks for any known problems that you can eliminate so the operation can succeed. The checks that are performed are developed from customer input on the previous problems that were encountered during installations and upgrades. NetBackup can update the checker whenever new customer feedback is received. Refreshes are not dependent on a NetBackup release. If your server can connect to telemetry.veritas.com, NetBackup automatically updates the checker with the latest version when the installation or the upgrade starts.

One of the tests that is performed is a comparison of the locally installed Emergency Engineering Binary (EEB) updates with the fixes included with the version of NetBackup being installed. If any of the preinstall tests fail, a message appears to indicate what type of action is required.

Some test failures are considered minor and let you continue with the installation or the upgrade. Critical test failures prevent the installation or the upgrade from happening. The output informs you that other action must be taken before you can proceed safely with the installation or the upgrade.

The preinstall check results are stored in the following locations:

  • Linux

    In the installation trace file in the following path:

    /usr/openv/tmp

  • Windows

    In the following directories:

    %ALLUSERSPROFILE%\Cohesity\NetBackup\InstallSummary\

    %ALLUSERSPROFILE%\Cohesity\NetBackup\InstallLogs

    More information about the InstallLogs directory is available: See About log file directory changes.
